Filed: 1964-10-05
Abstract: 1,091,784. Pulse discriminators. RANK BUSH MURPHY Ltd. Oct. 5, 1965 [Oct. 5, 1964], No. 40533/64. Heading H3T. A pulse amplitude discriminator comprises two monostable tunnel diode circuits in cascade, the dead time of the second being greater than that of the first. The discriminator may be inserted between the amplifier and the counter of a radiation-detecting system. The output of the amplifier 2 is passed through a diode 12 which limits the (negative) pulses to the tunnel diodes and prevents a large pulse from holding the latter on after the termination of the dead period. The first tunnel diode 22 acts as a threshold device and is turned on by a pulse of sufficient amplitude. The change in voltage so produced is reflected from the end of a delay line 24 and turns the tunnel diode off again. When this happens, an isolating diode 28 is turned off and the second tunnel diode 32, which was on, is now turned off. A similar delay line 34 reflects the pulse back to the tunnel diode 32 and turns it on again. The resolution time of the circuit is fixed by the delay line of the second stage since if a pulse turns the first tunnel diode on while the second is off, nothing will happen. Bias resistors 38, 40 for the diode 28 may not be necessary.

Title: Carding machine
IPC: D01G15/46
Filed: 1965-09-29
Abstract: 1,079,379. Carding engine. GUNTER & COOKE Inc. Sept. 29, 1965 [Oct. 2, 1964], No. 41331/65. Headings D1F and DIN. [Also in Division F2] In a carding machine a pair of smooth rolls 32, 33 provided adjacent the doffer 16 is weighted by magnetic means. Roll 32 has a small diameter e.g. one twelfth of the doffer roll diameter and removes the carded web from the doffer to pass between the nip formed between itself and roll 33. For natural fibres the rolls 32, 33 carry out a trash crushing function and the nip pressure is made high by incorporating the magnetic means (e.g. a series of magnets (47), Fig. 4, not shown, and pole pieces (48), (49)) within the roll 33: alternatively if synthetic fibres are treated the desired nip, pressure is less and the magnetic means in the form of smaller magnets are incorporated in the smaller diameter roll 32. A shunt bar structure 51 (Fig. 3 not shown) may be provided to regulate the nip pressure. The magnets may be permanent alnico magnets but electromagnetic means could be used. The rolls 32, 33 are mounted on adjustably positioned brackets (35) (Fig. 3), the roll 32 being carried by plates (39) adjustably pivoted on brackets (35) at eccentric mountings (40). Doctor blades 42, 43 are provided for the rolls. Doffer roll 16 is smaller than is conventional e.g. one quarter the diametric size of the cylinder 14 to provide a longer path of the web W to the condenser 55 and calender rolls 54. Doffer roll 16 is driven from the cylinder via paths 61, 60, 59 and drives roll 33 (and hence roll 32) via path 52. A device 58 providing two speeds and a neutral links the drive paths 60, 59 and may be operated from the front of the machine by a lever 78. Thus the doffer and the elements following it may be brought to a slow speed e.g. when the web end needs to be threaded through the machine. The doffer 16 is provided with wire clothing and special conditions for the angle of the teeth are described to ensure that the doffer teeth (34) (Fig. 2, not shown) readily shed the web at take-off. The position of doffer 16 is adjustable. A plate 20 is provided above doffer 16 and closely approaches a plate 18 extending about the cylinder 14 to form a slot 24 in the region of high pressure adjacent the doffer point. A hood 22, duct 28 and blower unit 29 are provided to draw air from the slot 24 and means may be provided to collect the fly in the air. A similar arrangement is provided at the lickerin 13. The plate 20 converges with the doffer surface towards the point of take-off.
